CONTAINER AND MANUFACTURE THEREOF.

Application filed September 24,1987. Serial No. 221,785.

This invention relates to improvements in contamers and the manufacture thereof, and

more especially to a container with a discharge opening having a readily removable closure.

One of the features of myinvention is the provision of such a discharge opening which is easily and hermetically sealed after the container is filled, but which may be easily opened by the consumer.

In that form of device embodying the features of my invention shown in accompanying drawings, Figure 1 is a view in perspective of a completed container, Fig. 2

1 is a vertical sectional view of the cover for the discharge openin showing the same before being a plied, spective of t e discharge opening showing the same before applying the cover, Figs. 4 and 5 are vertical sectional views showing two steps in the applying of the cover tothe opening, and Fig. 6 is'a plan view of the ordinary key used bythe consumer in removing the cover from the discharge openmg.

In the practice of my invention, the top of the can as indicated by 10 is first provided with a discharge opening 11 surrounded by the annular upstanding flange 12. 13 indicates a circular cover for the discharge opening which is provided with an upstanding ridge 16 providing a groove underneath preferably filled with a suitable sealing compound or cement 14."

, In the next stp of mainifacture, the cover 13 is applied over the-opening, the flange 12 extending up into ridge 16 and becoming embodied in the sealing compound 14.

After the parts are in the position shown in Fig. 4:, a press 17 is used to press the upstanding ridge 16 outwardly and flatten it" down as shown in' F-ig. 5, thus making a tight seal.

The cover 13 is preferably provided with a narrow marginal flange 18 around its edge and at one point this flange 'is extended to form a tongue 19.

20 indicates the ordinary type of key provided with a slot 21 adapted to embrace the tongue or tab 19. In order to remove the cover 13 from the discharge opening the key is applied and the cap wound upon the same in the usual manner, such winding ig. 3 is a view in perserving to tear the same loose from the dischar e opening.-

ile I haveshown and described certain embodiments of my invention, it is to be understood that it IS capable of many modifications. Changes, "therefore, in v the construction and arrangement may be made without departing from the spirit and scope of the invention disclosed in the appended claims, in which it is my intention to claim all novelty in my invention as broadly as possible in View of the prior art.

What I claim as new, and. desire to secure by Letters Patent, is k 1. A container having a discharge openmg in a wall thereof, and aremovable cover for said discharge opening, said cover attached to said wall by an outwardl extending flange surrounding the discharge opening, said flange projecting into and tightly embraced by an outwardly extending flattened hollow ridge in the cover.

2. A container having a discharge opening in a. wall thereof, and a cover for said discharge openin attached to said wall and held in place y a flange surrounding the discharge opening and extendin up into a ridge formed in the cover, 'sai ridge and flange being pressed downwardly and outwardly tightly against the wall to cause the ridge to lock the flange therein and hold the same tightly.

.3. The process of attaching a cover to a discharge opening in a wall consisting of providing an upstanding peripheral flange surrounding said opening in the wall, providing the cover with an upstanding hollow ridge adapted to receive said flange, appl ing the cover over the openin to cause t e flange to extend up into the ollow ridge, and pressing downwardly the ridge 'and flange against the wall into a plane sub- 95 stantially parallel with the wall to cause the ridge to be compressed, to squeeze theflange therein.

4. The process of attaching a cover to a discharge opening in a wall consisting of providing an upstanding peripheral flange surrounding sald opening, providing t e cover with an upstanding hollow rid adapted to receive said flange, applyin t e cover over the opening to cause the to extend up into the ridge, and presing ange p downwardly and outwardly theridge and flange against the wall to cause the ridge to be compressed,-t,o squeeze the flange therein.

5. A container having a discharge open- 5 ing in the wall thereof, and a removable:

cover .for said discharge opening, said cover attached to said wall by an outwardly extending flange surrounding the discharge opening, said flange projecting into and tightly embraced by an outwardly extending flattened hollow ridge in the cover lying against said wall.

In Witness whereof, I have hereunto set my hand this 21st day of September, 1927.
